madVR - high quality video renderer (GPU assisted)

[Dodgexander]

I see there's been a lot of discussion since I last posted about my issue but I have done some more testing, this time manually putting my PC into sleep. The results are different than when my monitor first goes to sleep and the PC sleeps afterwards.

With MadVR and zoom player or mpc-hc the results are the same.

If the PC does go to standby and return the video is always green and I have to restart the player for it to work again.

With mpc-hc using the EVR it doesn't happen.

It also doesn't happen 100% all the time I manually sleep but does when I leave my computer to sleep (monitor turned off first).

The bsod I get that reboots the PC before the PC is allowed to go into sleep points to ntoskrnl.exe 14a510 but when the PC bsods on return from sleep the bsod points to dxgmms2 blaming the nvidia driver.

For a while I didn't notice this was related to madVR so I've carried out various steps to solve it already. I've made sure there's no memory fault with my PC by running memtest86 for 48h, I've checked with prime 95 for 24h and I've monitored temperatures to make sure they aren't too high. First thing I did was do a complete clean install of the nvidia drivers.

I'm not sure why I have this silly problem but it would be great to get to the bottom of it.

Anyone have an idea what it could be? Is my graphics card faulty?

Catmull-rom is the same as Bicubic 50 which is soft. There is nothing wrong with using Bicubic 60 for chroma upscaling. I use it by choice with jinc for luma because it looks better than jinc/jinc to me, and also because when it comes to colour, catmull-rom and bicubic are the chromas that match the colours of nearest-neighbour. I don't know about the newest algos as I never tested and they require more gpu anyway. The goal is not to make stuff sharp as a tack. When image editing, good quality unsharp masking after downscaling stops at the point where the sharpen just barely becomes visible via preview on and off, this is usually on an case by case basis for dialing in the numbers so I do agree with the selection of 60 here, because 75 was already on the sharper side.

I'd start with the system BIOS first. Reset it and test then look for an updated BIOS for the motherboard and GPU.

I had DP to miniDP and screen always bugged on me if I left player on pause and left pc to switch screen off. Screen didn't wake up 3 out of 10 times. I got DP-DP cable it went away(for now), so I think it's driver issue in my case. It is also happening only on w10.
Just do not leave player running when you need to step away from PC.
Also it's generally bad to let PC go to sleep, it somewhat works for laptops because battery life, but there is no need to do that with PC. So many things can go wrong with modern GPU drivers, probably that's what happening, you are not saving word document into RAM, it's a bit more complicated with rendering I think.
Set it do disable display and never go to sleep, most safe option.

I've heard a lot of feedback about the new settings dialog organization. Thanks, guys.

But I don't remember anybody commenting yet on the new NGU-Low quality level. It's faster but softer than the old NGU-Low. But is it still "acceptable"? How's sharpness, aliasing, ringing etc for you? Is it worthy of the "NGU" sticker?
I think NGU-Low is great for 720p->1080p upscaling. Switching between NGU-Low and NGU-Very High I see little to no difference with 720p content, except for a very very (did I say very?) small increase in sharpness.

I am now able to run NGU-Low on 720p60 videos, where I couldn't use any NGU levels before with my HD 7770. It's also significantly faster than Jinc+SR2.

There is a bigger difference with SD videos. There is a noticeable quality increase between NGU-Low and NGU-Med, with then smaller increases all the way up to Very High. Surprisingly I am able to use NGU-High on 480p60 videos with render times around 10ms, so it's not much of an issue.

If you are somehow able to make NGU-Low sharper without increasing gpu usage, that would be good though.

Maybe Catmull should be used in place of bicubic150? I've never a/b them though. I thought we were all happy with Catmull, especially as as downscaler, for a long time :cool:
Please no. Bicubic 150 AR is a very fast and good alternative to SSIM. It's even better in some ways judging from the pics posted above (we are talking microscopic zooming levels anyways, in practical terms they are almost the same). After upscaling good content with NGU, I don't want to then make it blurrier with Catmull-Rom.

Yes, I have a similar problem. madVR seems to lock the player in memory, you can't end the process and you have to literally turn the power off and back on again because it locks such that you can't restart (restart just hangs).

I think I might start another thread specifically targetting any issues with madVR and the hardware involved. I will emphatically state the purpose of the thread so people don't try an argue that it works fine for them so there isn't a problem. From what I have found, the issues seem to be more prevalent on Geforce GTX 10xx models and Radeon RX models (the 400 series). The old R9-280X worked beautifully and on affriend's R9-280X (different other hardware though) runs beautifully with similar settings, so it will be interesting with the responses.

It's not madvr related. For example if you send PC to sleep/screen switch off through GPU while running a game same thing will happen.

GPU drivers must not go to sleep on load.

With the R9-280X I could let the computer go to sleep if I had it paused in D3D 11 Exclusive mode, or in a windowed mode D3D 11 etc without any issues. Therefore, I know that you can let it do it, the issue and others appears to be with newer Geforce and AMD cards.

If it doesn't work for you, then you are just another person that is affected by this!

Well yeah, but it's drivers+windows 10 that does this, madvr may trigger it more often but it happens with everything else anyway.

[Razoola]

I wanted to give some feedback on the new settings layout. Personally I do not like it much as I feel its a little confusing. At the same time though I can see the original way was probably not the best either simply because it has elvolved over time. Both ways kind of over complicate the settings. I have a suggestion of a settings layout that may work but at the same time I guess some may not like it and it would be alot of work for madshi given it probably needs the current system demolished and rebuilt...

My idea is under 'scaling algorithms' there should be three sub option windows.

- Movie Original
- Movie Upscaling
- Movie Downscaling

Under each of these settings are dropdown boxes (much like the new doubling options) and other settings that follow the rendering process, from top of page to bottom of page. The user can then choose how chroma / doubling and everything else is handled as it passes through the rendering process. Movie original would be for example where a 1080p move is output to a 1080p disaply. The other two are self explaining.

Would something like that be workable madshi? What do you power users think? I feel it would simplify the options greatly but thats just my opinion.

[ashlar42]

Exactly.

Here you can see a comparison between Jinc, Lanczos3, Bicubic150 and SSim1D100 for downscaling after 2x supersampling with NGU:

And zoomed:

Make your choice. For me it is Lanczos3 because Bicubic150 has too much aliasing and Jinc is a little bit too soft.I don't find Bicubic150 to be aliased at 100% zoom, I just find it pleasantly sharper.

[Ver Greeneyes]

Looking at Neo-XP's zoomed in comparison, there are some spots where SSIM seems to preserve the structure of the upscale better, like a spot on the edge of the woman's face between her eyebrow and eye (on the right side). Other than that it actually seems slightly softer than Bicubic150, but I think the sharpness overall is somewhat more consistent. So I do think this proves that SSIM can make a visible difference, even if the number of pixel differences for a given image are small. Whether the trade off between letting people use all the power of their GPUs and keeping them from wasting power on inconsequential things is worth it is another question.

There is a weird dot on the left eye(if looking at picture) center with SSIM though. just a glitch?

[Neo-XP]

I could live with Bicubic150 for downscaling, it just accentuate the sharpening of Lanczos3 (but the dark halos are increased too). Lanczos3 is just sharp enough for me.

I will test all the algorithms with a bad source material. It should be easier too see all the qualities and defaults of each one.

[Ver Greeneyes]

Do you mean around the bottom right corner of the highlight (the window reflection) in her pupil? Yeah that looks a little weird, might be there in the upscale too though.

[clsid]

If the PC does go to standby and return the video is always green and I have to restart the player for it to work again.

With mpc-hc using the EVR it doesn't happen.
I think this is probably something that madshi can fix.

EVR-CP has similar issues after sleep/hibernate, which can be solved by turning on this option:
options > playback > output > reinitialize when changing display

Relevant code:
https://github.com/mpc-hc/mpc-hc/blob/develop/src/filters/renderer/VideoRenderers/DX9AllocatorPresenter.cpp (starts at line 1627)

[clsid]

Hi madshi, since you are now also working on simplifying the settings GUI, I have some ideas regarding the presets/profiles.

1) Get rid of the profile groups. It is just unnecessarily complex. Just let presets cover the whole group in each section.
2) On the main level in the GUI (e.g. scaling algorithms page) show a list of all presets in that section. Have buttons to remove and duplicate a preset.
3) Always have at least one preset. For example called "default". This one can't be removed. It is used as a fallback.
4) Display all settings pages just once. Have a dropdown box somewhere at the top to select the "current" preset. Simpler GUI and one can quickly compare settings of different presets. Have an entry called "new" at the bottom of the list. When selected, this takes the user to the preset creation page of that section.
5) Don't use a profile selection script, but instead give each preset a boolean statement that determines if it should get loaded. This has two benefits. First of all, presets become fully independent, making them easy to share/exchange. So we can start making "Doom9 community approved (TM)" optimized presets in the near future. Secondly, it is much easier to have a large number of presets. Non-programmers are often already struggling with relatively simple profile selection scripts. Given the increasing popularity of 4k and 60fps video, plus the availability of HDR and 3D functionality in madvr, the amount of presents can be significant in case of the true enthusiasts.
6) Add buttons to import/export a preset. Preferably in a (human readable) text-based format (xml/ini) for easy sharing.
7) Add a right-click menu to the boolean statement field of the preset. This is used to quickly insert commonly used variables (srcWidth, deintFps, etc) and could even have submenus for stuff like "(deintFps > 31)".

[Uoppi]

Otherwise, if you can run it, I find NGU high (the new high, old medium) is a breakpoint where the image becomes noticeably better.

Do you mean for luma? Or also for chroma? I tend not want to "waste" resources on chroma by going all-out without visible benefit.

I like NGU a lot but not so much for SD -> 1080p. The picture is too "frizzy" or oversharp. I'll need to play with soften edges, I guess.

I'm not opposed to this, but it does mean the order in which the profiles are listed becomes significant - the first profile to match a rule would be loaded. Right now the profile selection script determines this ordering; that would need to be replaced with something less generic (like a configurable box listing the profiles in the order they will be tried).

[clsid]

Yes, of course, the order of the list of presets should preferably be customizable. That is easy to implement (with up/down button for moving a selected preset).

But ideally the loading rule of a preset is specific enough to avoid multiple matches. At least when we start creating presets for others.

The idea is to eventually have a few presets for each common type of situation (e.g. 720p23 -> 1080p23) with increasing quality/complexity. Plus a fixed set of sample files for testing. Plus a dedicated topic for testing results. So everyone can compare rendertimes and pick the most suitable preset for their hardware. Ultimately a little tool that automatically sets proper presets. Unless madshi beats us with some kind of automated performance based magic.

[nevcairiel]

As a programmer, I like the profile selection scripts. I have one single view where I can see which rules determine which profiles are used. Having to check every single profile and only seeing one line at a time would be quite a step back, imho.
As a compromise it could offer an "advanced" and "simple" mode, where in simple mode it just constructs the script from the individual lines, and in advanced mode, let me write it.

[clsid]

Yes, that would be a reasonable compromise.

Perhaps additionally (at a later stage) a preset "test" function could be added? A test button that open a dialog where you can specify the various parameters such as srcwidth/srcheight (textbox), fps (dropdown), filename, HDR (checkbox), etc. That then shows which preset(s) matches the chosen values.

[JarrettH]

How do you even tell what is what at 800% zoom?

[Warner306]

I don't find Bicubic150 to be aliased at 100% zoom, I just find it pleasantly sharper.

Same here. I like Bicubic150 and SSIM.

That's for downscaling. Although, the difference is so small I don't really care.

You can easily see there that Bicubic150 produce a lot of aliasing and other ugly artifacts.
That is why I use Lanczos3 after luma doubling with NGU and why it should be available in madVR's new versions, for upscaling and downscaling.

Literally no logic there.

[Neo-XP]

Literally no logic there.

Maybe I wasn't explicit enough. I used a bad source material to highlight the defaults of each algorithm. When used for luma doubling, NGU will produce some artifacts that will be increased by the algorithm that you put after it, for upscaling and downscaling. Jinc is also very good if you want a clean result, but the rendering times make it not relevant for me.

You need to show us the source. Something is definitely weird here, as the aliasing "block" size is much larger than a single pixel, if you compare to native resolution in the OSD. It's like the source is nearest-neighbor doubled/tripled or something.

Do you mean for luma? Or also for chroma? I tend not want to "waste" resources on chroma by going all-out without visible benefit.

Sorry, should have specified. I meant luma. I don't use NGU for chroma, because it's almost invariably filled with compression artifacts which the algorithm thinks is real detail a lot of the time. For very clean sources, it's quite nice, but similar results can be achieved for faster using Recon Soft or bilateral.

NGU is best for source content 720p and up scaled to either 1080p or 1440p. I don't have 4k and cannot comment. For SD and lower, nnedi3 is still king (with SR off if source is dirty enough), and could be improved with Add Grain if madshi decides to allow the combination.

Pretty sure that bicubic150 is bugging out here - there is no way in hell it should look that bad. Dunno if it's your setup or the algo though. Maybe you can share a short sample?

[Dodgexander]

I'd start with the system BIOS first. Reset it and test then look for an updated BIOS for the motherboard and GPU.
Thanks, I did a bit more troubleshooting and found it seems to go away if I set my memory to its lowest timing. I am using 4x2gb sticks which I think must be straining my northbridge (Hypertransport?? since I have an AMD board) so I am going to continue running with a low frequency on the ram and see how it goes. I may need to raise the northbridge clock and/or frequency to get stable at the rams normal timings. Its so strange because I ran memtest86 for 48 hours and prime and it found no faults. Usually it catches faults between the CPU and Memory but this time it doesn't. At least I have a way to test it that works 70% of the time! thanks very much for your help.

Edit* spoke to soon. I tested going in to standby manually several times and thought it was fixed, however again when I left my computer with video paused in mpc hc and madvr it bsod and rebooted with ntoskrnl.exe VIDEO_SCHEDULER_INTERNAL_ERROR

All of my BSODs seem to be related to 3 things causing it
watchdog.sys
nviddmkm.sys
ntoskrnl.exe

all are VIDEO_SCHEDULER_INTERNAL_ERROR

i'm starting to wonder if it is driver related.

I had DP to miniDP and screen always bugged on me if I left player on pause and left pc to switch screen off. Screen didn't wake up 3 out of 10 times. I got DP-DP cable it went away(for now), so I think it's driver issue in my case. It is also happening only on w10.
Just do not leave player running when you need to step away from PC.
Also it's generally bad to let PC go to sleep, it somewhat works for laptops because battery life, but there is no need to do that with PC. So many things can go wrong with modern GPU drivers, probably that's what happening, you are not saving word document into RAM, it's a bit more complicated with rendering I think.
Set it do disable display and never go to sleep, most safe option.
Leaving it on all the time is something I debated but I am on and off my PC all day so it would save a considerable amount of power in the long term if the PC would just turn itself into standby. At the moment that is what I keep having to do, just keep forgetting not to leave it playing.

I'm not sure in my case it is a driver related problem though because reducing my memory frequency seems to have fixed it (so far)

turns out despite testing it doesn't help if I leave my computer. Seemed to work ok going in and out of standby manually though.

I started a new thread here for specific issues like this:
http://forum.doom9.org/showthread.php?p=1788137

I do call it an issue because it does not affect the R9-280X with all other things equal. It seems to only affect newer cards from Nvidia and AMD. If it is driver related then tracking down the cause will allow it to be reported via driver reporting :).

In my case I use a geforce 660 and it happens, i'm not sure its specific to recent nvidia cards anyway. I will post in your thread.

I think this is probably something that madshi can fix.

EVR-CP has similar issues after sleep/hibernate, which can be solved by turning on this option:
options > playback > output > reinitialize when changing display

Relevant code:
https://github.com/mpc-hc/mpc-hc/blob/develop/src/filters/renderer/VideoRenderers/DX9AllocatorPresenter.cpp (starts at line 1627)

Thanks, that would be awesome!

Your source is very obviously not larger than 1440p. You shouldn't compare downscales with it, unless you're using nnedi3 or ngu.

Edit: Didn't catch this at first, but you're using the algorithms to *upscale* according to the OSD. Bicubic 150 shouldn't be used to upscale, ever. It probably shouldn't even be selectable in madvr. Of course bicubic 150 looks like garbage on upscale.

Agreed, terrible method used for the given situation... That comparison makes zero sense

Hi, I'm still getting a bug on the latest few versions where screenshots taken in MPC-HC just result in a white garbled mess. The only workaround is to scale the video first.

I'm using a GTX 1060, but it's been constant among driver versions also.

May I ask whether it will produce a better quality image if I use

-NGU-high chroma for upscaling to produce a 1080p image then use an AV-receiver to upscale it to 4K, or

-use Catmull-Rom for chroma upscaling and NGU-low for luma doubling to upscale a 1080p image to 4K?

I do not have a 4K monitor at the moment but I plan to get one in the near future but my GPU isn't quite powerful enough to use anything higher than NGU-low for luma doubling to upscale a 1080p image to 4K, so which is a better option?

[BluesFanUK]

I've got a 1440p monitor and i'm struggling to tell the difference between any of the settings now (and no I don't need glasses).

Is this only beneficial to Anime or something?

[Warner306]

For those interested, Kodi DSPlayer has been updated to the latest version of Kodi (v17) and is now compatible with the new settings dialogs.

This is a surprise release. I'm not sure if it will continue to have support in the future.

Feedback on NGU Low:

NGU low is great in itself. I actually like its lesser sharpness as compared to the higher versions of NGU. I tend to get distracted by the disproportion that NGU high and NGU very high create in the image in terms of definition of the edges and the texture. Even “soften edges” doesn’t help much there. NGU low is better in that regard. The performance is great too.

I'm sorry for bothering everyone with my petty problem, but what could be the cause of madVR not detecting any display device at all? I've noticed that madVR stopped switching frequencies, then I've noticed that the display that I was using isn't marked as active (bold) in madVR. Then I deleted all devices from the list. Tries resetting to defaults, installing/uninstalling madVR, checked my computer for any unnecessary codecs to no avail. The list is now still empty under "Devices" in madVR.

I know it's completely off-topic, but I can't connect BlueSkyFRC filter with the playback chain. What's the standard troubleshooting procedure in that case?

[AngelGraves13]

It's a shame that NGU isn't scalable and just doubles, requiring huge resources to downscale back to native resolution. If that could be changed, it would actually be useable for all content and not just content that needs to be doubled.

1080p->1440p uses a ton of GPU resources, so much so that I've decided against using it as it causes my GPU to get rather hot and the fans are just too loud to enjoy the movie.

Guess I'll stick with ReconSoft for Chroma and Jinc for all my scaling needs until something better comes along.

[aufkrawall]

Reconstruction for chroma is quite expensive too and has little benefit over jinc, imho.

I've just tried to reply to all the recent posts, but I'm getting server error 500 if I try to quote anybody. So the replies will have to wait until the forum is fixed again.

[optimist]

@Warner306 Wow this is really good news even if aracnoz doesn't continue to support it. Maybe he will release an update for major Kodi release.

On topic: NGU is working nicely with my Nvidia 1070. Thank you madshi for this awesome algo. I have a Panasonic plasma TV and NGU doesn't seem overly sharp with very high setting. I mostly watch HD movies and tv series, not much anime. Like others I have some low quality SD content and I have to use softcubic for them to hide the compression artifact, NGU is not suitable for them. Some thing to mask the compression artifact would be much appreciated.

I can tell the difference from upscaling 1080 on 1440 monitor if I am sitting 15 inches from the screen, that's about it for me.

[Alamei]

This might be a silly question, but how are you all getting that rendering time step-by-step breakdown to show up in the stats? Is it a recent feature that was added?

[sneaker_ger]

Create an empty file "ShowRenderSteps" in the madvr folder.

[Alamei]

Excellent. Thank you for the quick response. I can normally just get the answers by searching the forum, but it currently seems to be glitching out and throwing 500 errors on half of the pages I look at (in addition to being upset with quote attempts, as madshi mentioned).

[Sp00kyFox]

is the deringing filter of madvr under "processing/artifact removal" a custom filter or is there an avisynth implementation of it? I'd like to use it in a script of mine.

[Asmodian]

It is a custom filter.
